1,used for carbon steel 2,good process and mechanical properties 3,applied to ship steel welding

1, ER70S-6 is a copper low alloy steel wire with all position welding.

2,The wire has a very good welding performance and the weld metal shows lower temperature impact toughness.

3,It is mainly used for butt and fillet welding structures shipping steels and low alloy steels ,suchasships ,containers ,vehicles, engineering & construction machinery ,bridges and so on. 

 

 

 

 

The tensile strength of melted metal from those carbon steel welding rods should be less than 500MPa.They are the most widely-used rods. The are mainly used in the welding of carbon steel and low-strength low-alloy steel, such as 16Mn,09Mn2Si and etc. 422      GB E4303 equals JIS D4303 Index Chemical Composition of Deposited Metal(%) C Mn Si S P 0.06-0.15 1.40-1.85  0.80-1.15 ≤0.035 ≤0.250 Mechanical Properties of Deposited Metal Iterms Tensile Strength (MPa) Yield Point (MPa) Elongation % Impact Value(J) 0 Standard ≥420 ≥330 ≥22 ≥27 Typical 430-490 ≥330 22-32 70-115 Sizes, pieces & Recommended Current(AC or DC) Diameter (mm) 2.0 2.5 3.2 4.0 5.0 Current(A) 40-70 70-90 90-130 160-210 220-270                   Note: If the welding rods is affected with damp, it should be baked around 30-60mins at 150 .
